l Claim.

The present invention relates to implements, and more particularly to an applier for applying a length of an adhesive tape to a surface.

An object of the present invention is to pro-V vide an applier carrying a supply roll of adhesive tape, by means of which a length of adhesive tape may be applied to a surface by simply moving the applier along such a surface and severing thereafter said length of adhesive tape from the supply roll.

A further object of the present invention is to provide an applier for applying adhesive tape to a surface by movement along such a surface, said applier being equipped with cutting means in such a manner, that, after the application of a length of adhesive tape to a surface, said length of adhesive tape may be readily severed from the supply roll of adhesive tape carried by the applier.

Another obiect of the present invention -is to provide an applier for applying a length of adhesive tape to a surface, by means of which practically nostress is exerted on such a surface during the application ofthe adhesive tape, so that the adhesive tape may be applied without damage to or distortion of the surface, if the latter consists of a loose sheet of paper for example.

A further object of thepresent invention is to provide an applier for applying a, length oi' adhesive tape to' a surface, by means of which such a length of adhesive tape may be smoothly applied from end to end to such a surface.

Another object of the present invention is to provide an applier for applying a .length of adhesive tape to a surface, which does not require the gripping of the adhesive tapeby hand for theperformance oi the application of the adhesive tape to the surface.

A further object of the present invention is to provide an applier for applying a length of ad-A according to the invention, in position for applying tape to a surface, some parts being broken away.

2 Fig. 2 is a sectional side View of the applier shown in Fig. 1, wherein, however, the elements thereof are in a position for cutting the tape, and

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2.

'Referring now to Figs. 1-3, 20 generally indicates the main body or carrier of an applier according to the invention. Said carrier 20 comprises a member 22 of suitable rigid material having a stud. 24 extending into a cavity 26. Furthermore, said member 22 is provided with a pin 28 integral with said member 22. A cover plate 30 having a bore 32 for engagement with the pin 28 may be attached to the member 22 by means of a screw 34.

An applying roller 36 having a layer 38 of resilient material, for example rubber, is rotatably arranged on the pin 28. A transverse bar or guard 40 substantially in the shape of a U is rigidly lconnected at its ends with the member 22 and the pin 28. The base of said U-shaped guard 40 extends substantially parallel to the circumference of the applying roller 36 at a distance therefrom.

The carrier 22 is pivotally connected with In the embodiment shown in thek drawings, said pivotal connection 'Il is in alignment with the axis ofthe applying roller 36.

One end of astrip-like length of resilient material 90 is secured to the carrier 20 by means of screws 92. Ihe other end portion of said resilient strip'ilil is slidably engaged withv a bearing of the support 68 and has at its free end a cutting edge 43.

Said resilient strip tends to urge the carrier 20 and support 68 into the spread position shown in' Fig. 1. Said spread position is limited by an abutment of a pin 15 mounted on the carrier 20 with the upper end of a slot 11 arranged in the support Gil.-

After removal of the cover 3l),A a supply roll 58 of an adhesive tape, which may be of any .customary type, for example, of the cellulose type known in the trade as Scotch-tape or of the fabric type, may be readily rotatably mounted on the stud 24 of the member 22. The end of the adhesive tape 60 is laid along the surfacev B2 of the member 22 and around a portion of the circumference of the applying roller 36 as shown in Fig. 2. 0f course, the non-sticky surface of. the adhesive tape 6U is brought into contact with said surface 62 and the circumference of the applying roller V36. The end of the adhesive tape B0 passes between the guard 40 and the applying roller 38. According to Fig. 2, more than a quarter of the circumference of the applying roller 36 is engaged by the adhesive tape 68.

Upon re-attachment of the cover 30, the applier is ready for use.

When it is desired to apply a length of adhesive tape to a surface, for example a sheet of paper or a card-board, the carrier of the applier is held at an angle to the surface 64 as shown in Fig. 1. The end 66 of the adhesive tape 60 is applied to the surface 64 |by exerting a slight pressure on said tape by means of the roller 36. Thereupon, the carrier 20 of the applier is moved along the surface 64 in the direc-` tion of the arrow A. Such a movement of the applier causes a rolling of the applying roller 36 over the surface 64, whereby a length of adhesive tape 60 is applied to the surface 64. During said rolling of the applying roller 36 over the surface 64, the rotating roller 36 engaged with the adhesive tape 60 draws of! adhesive tape from the supply roll 58. During this drawingoff procedure the supply roll 58 is prevented from over-running by the adhesion between the drawnoif tape 60 and the next layer oi. tape on the supply roll.

' As best shown in Fig. 3, preferably the width of the applying roller 36 is somewhat larger than the width of the adhesive tape 60. Thus, a portion of the applying roller 36 is in direct contact with the surface 64 during the rolling along of the applier for the application of a length of adhesive tape to said surface. Therefore, the

applying roller slightly pressed against the surface 64 is driven by the friction between the surface 64 and the applying roller 36 during the movement of the applier in the direction of the arrow A (Fig. 1). Owing to the fact that the applying roller 36 presses the adhesive tape onto the surface 64 and causes the drawing-off of tape from the supply roll by its own rotation, practically no stress is exerted on the surface 64 during the application of adhesive tape by means of the applier shown in the drawings. Therefore, the application of adhesive tape to the surface 64 by means of the applier will not cause any-damage to the surface; for example, if such a surface consists of a rather thin sheet of paper, said paper will not be torn or mutilated during the application of adhesive tape by the applier.

After a sufcient length of adhesive tape 60 has been applied to the surface 64, the applier is lowered, so that the support 68 comes into engagement with said surface, whereupon the carrier 20 is pressed downwardly against the action of the strip-like spring 96. During the thus resultin',r rocking of the carrier 26 about the pivot 1|, Ythe cutting edge 43 of the strip-like spring 96 is 'advanced from its retracted position (shown in Fig. 1) to the right into its advanced tapecutting position shown in Figs. 2 and 3, whereby the tape is cut. Upon a release .of the carrier 20, the latter is automatically returned into its spread position relative to the support 68 (shown in Fig. 1) and the cutting edge 43 of the striplike spring 90 is automatically returned into its retracted position by the action of said striplike spring 90.

After the cutting of the tape the guard 40 near to the sticky surface of the end 66a (Fig. 2)y of the tape prevents the 'latter from an undesired backing-up; the applier is ready for applying another length of tape to a surface.

When such another length of tape shall be applied to a surface, the end 64a (see Fis. 2) may be readily used in the manner described above in connection with the end 66 (see Fig. 1) for applying the adhesive tape to the surface by holding the applier in the position shown in Fig. l and pressing said end against the surface throughthe medium of the applying roller 36.

As will be readily understood from above, it is unnecessary to touch the sticky adhesive tape to be applied to a surface with the fingers of a hand. The application of a length of adhesive tape to a surface is carried out merely by an appropriate manipulation of the body 20 of the applier.

I have described a preferred embodiment of my invention, but it is understood that this disclosure is for the purpose of illustration and that various omissions or changes in shape, proportion and arrangement of parts, as well as the substitution of equivalent elements for those herein shown and described may be made without departing from the spirit and scope of the invention as set forth in the appended claim.

What I claim is:

An applicator for applying a length of an adhesive tape to a surface, comprising in combination: carrying means including a body and a support for said body movably connected with each other, holding means on said carrying means for rotatablyholding a supply roll of adhesive tape. 1an applying roller rotatably arranged on said carrying means in a position for being engaged at a portion of its circumference by tape coming from such a supplyroll, said applying roller being 'arranged for being rolled over a surface by a displacing manipulation of said carrying means along said surface and for applying at the same time adhesive tape to said surface. and a strip-like length of resilient material -attached at one of its ends to one of said relatively movable support and body and loosely engaged at a portion of its length with the other of said f last mentioned elements for urging same into a spread position at a predetermined angle relative to each other, said strip-like length of resilient material being provided with a cutting edge at its free end slidably mounted` on said support, said cutting edge being reciprocable between a retracted position and an advanced tape-cutting position, said cutting edge being in its retracted position when said pivotally connected support and body are at said predetermined angle relative to each other, and said cutting edge being automatically displaced into its advanced tape-cutting position upon an action of said carrier on said engaging portion of said strip-like length of resilient material during a change of said angle by a movement of said body relative to said support.
